Abstract: This review summarizes the intermolecular PdII-catalyzed dehydrogenation procedures leading to regioselective coupling of alcohols with (hetero)arenes bearing tethered coordinating groups. Unusual oxidative conditions of catalyst regeneration are required, and the optimum oxidant varies with the… read more here.

Abstract: A new strategy has been developed for the first time for the synthesis of spirofluorenyl benzosultams through the annulation of aryl iodides with cyclic N-sulfonyl ketimines. This method involves a readily available Pd(II) catalyst for… read more here.
